So, the Merc's muffle, is 3 keys, as it said on the spreadsheet. The hat/misc is 4.99 plus tax, it'd be $5 +. So, 3 keys, is like $7. Would that means, you would gain great profit, if you sell that muffler for 3 keys? (If anyone would even buy). There's no dirty version of it so... What's so special about it? It's just a ugly piece of scraf.
